LOOM-SHUTTLE Specification of Letters Patent.

Patented June 22,1909.

Application filed January 25, 1909. Serial No. 473,957.

5 Massachusetts, have invented an Improvement in Loom-Shuttles, of which the following description, in connection lwitlii ,the accompanying drawings, is a specification, like letters onv thedrawings representing like l0 parts.

The invention to be hereinafter described relates to looin shuttles, and inore particularly to the general type known as self thread-l ing shuttles.

In a prior application filed by nie April 29, erial No. 429,803, there was shown, described and claimed a self threading shuttle for use iii so called filling replenishing looms, said shuttle being constructed and provided 20'With means whereby it assumes deliverable control of the filling on relative movement of the shuttle and thread end in a direction transverse to the length of the shuttle prior to being picked.

The present invention is a development of this, saine general character of shuttle, the aiins an objects of the invention being best presente( by the followingdescription and accompanying drawing, showing one forni of means for practical enibodinient thereof.

ln the drawings: Figure 1 is a top or plan view of thc delivery end of a looni shuttle show/ing the present invention associated therewith; Fig. 2 is a side elevation of the shuttle shown by- Fig. 1 Fig. 3 is a plan view similar t Fig. 1 with the threading block renioved,."the tip of the shuttle being broken away; Figs. 4 and 5 are detached views of the horn looking from different directions; Fig. 6

4U is a side elevation of the'threading block dctaehcd; Fig. 7 `is an end View of the threading block looking in the direction of the arrow e, Fig. 6; and Fig. 8 is a view similar to that of Fig. 7, looking in the direction of the arrow b, Fig. 6.v

The shuttle body Il is provided with the bobbin receiving opening 2, and at its delivery end is forn'ied with a wall '3,' which, in

connection with the-diagonal side 4 of the. threading block forms a substantially V-,

shaped opening, as indicated in Fig. 1. The wel 3 of the shuttle body inclines downwardly from the too of the shuttle. and in threading block, Figs. 6 and 7.

general contour' may turn forwardly or toward the front of the shuttle as it extends toward the shuttle tip, it being understood, of course, that the front of the shuttle isthat face thereof which contains the thread delivery eye 5. 'At its forward position 6, the

wall 3 nieets a Adepressed portion 7V in the shuttle body extending in a general direction longitudinally of the shuttle, the effect being, the vfrontwardly inclined portion .6 of the shuttle wall and the longitudinal portion 7 serve to position the exterior portion of the thread so that on movement of the shuttle the thread will engage beneath the beak of the threading block, as will presently appear. The thread delivery;eye 5 inay be formed in a suitable niaiiiierfaiid is herein preferably countcrsunk within theplane of the front face of the shuttle, and an opeiislot 8 leads frein the eye in a general direction toward the V-shaped opening hereinbefori-i inentioiied. lf desired a wear piece nia-y be disposed at each side of the delivery eye 5, said wear pieces being` preferably provided by pins f), 9, Figs.l 2 and 3. Between the delivery eye 5 and the depression 7, the shuttle body is or may be forincd with an upwardly projecting part 10, Figs. 1 and 2.

'lhe delivery end of the shuttle is provided with a suitable recess to receive the threading block 11, of the general construction iiidicated in Figs. (5, 7 and H. ln the present forni the threading block is provided with a base portion or bridge piece 12 adapted to extend transversely of the shuttle body in a seat 13 thereof, Fig. 3, said bridge piece having an upwardly extending lip 14 seated in a recess 15in the wall of the shuttle body, the construction being such that the exposed surface of the lip .14 does not )reject beyond or flush with the wall 3, which foi-ins part of the thread passage leading to the delivery eye. perforation 16 through which a suitable bolt I7, Figs. 1v and 2, niay pass to assist in holding the threading block in place. A seat 1S, preferably above the surface plane of vthe seat 13, is provided with a hole 19 to receive a stud 20 depending from a portion oll the Supported upon the recessed portion ofthe shuttle body and in front of the recess 13 or bridge piece 12is a friction pad 21, Fig. 3, so disposed as The bridge piece 12 is provided with a to act upon the thread as it passes from the bridge piece toward the delivery eye.

As indicated 'in Fig. 6, the threading block l1 has a web 22 extending forwardly from the bridge piece 13 and surmounted by a top or loop casting portion 23 generically characterized by a gradually Vdiminishing' or wedge-like formation, such that a loop of thread caught on said top or loop casting portion would ride off the end thereof Without unthreading the shuttle or breaking the thread by a pull on the thread exterior to the shuttle. l At its forward end the top or loop casting portion has a beak 24 turned toward the bottom and front of the shuttle body, its face 25 acting as a thread engaging and directing element to effect a deliverable control of the thread when the shuttle and eX- terior portion of the threading-block leading therefrom are relatively moved in a direction transverse to the length of the shuttle. The beak 24 extends somewhat below the surface of the shuttle body adjacent thereto, so that the thread having once passed beneath the beak in the manner stated, and the shuttle having thus assumed deliverable control of the thread, unthreading is prevented, as will be readily understood by those skilled in the art. lf desired, a metal guard a, may be secured to the body of the shuttle adjacent to or opposite the beak to prevent change in the established relation of the beak and Wall of the shuttle body below which the beak extends.

As previously stated, the thread passage leadin from near the end of the bobbin is forme( on one side by the inclined wall 3 of the shuttle body and on the other sid'e by the Wall 4 of the threading block. The wall 4 of the threading blocklnear its forward portion is provided with an overhang 26 forming a shoulderextending over the thread passage, said part thus acting to prevent rising of the thread when once it has found its proper position in the lower part of thepassageway.

Secured to the shuttle body forward of the threading block is the horn 27, Figs. 3, 4 and 5, having a toe 2S adapted to be securely seated in the shuttle body and a lip 29 at its upper portion adapted to engage a recess 30 in the 4top -or loop casting portion of the threading block l1. The horn 27 is formed of a hard metallic substance having a shoulder or thread retainer 31 beneath which the thread passes on its Way to the delivery eye 5J saidy om being preferably provided with an angularly disposed side extension or wing 32, the edge 33 of which is seated in the shuttle body, Figs. l, 3 and 4. The edge of the Wing 32 adjacent the body'34 of the horn is formed With a thread guiding'eye 35, the edge 36 of the wing being inclined or curved, Fig. 4, to

act as a thread director to direct the thread to the opening of the eye 35 as said thread is drawn r om the bobbilnil It wild be' noted eaaoiv that the end 37 of the eye producing portion of the wing is disposed adjacent the edge of the body 34 of the horn, and adjacent thereto said body of the horn has a bur or 4thread stop 3S which, in connection with the overhang 26 of the threading block, when the thread has once been caught by the eye 35, prevents disengagement of the thread therefrom.

By reference to Fig. 3, it will be noted that the body 34 of the horn is disposed at one side of and angularly with relation to the lengitudinal axis of the shuttle and is in clined from top to bottoni in a direction angularly away from the tip or end of the shuttle, such general disposition of the horn being conducive to more certainty of action in completion of thc threading operation, although it is to be understood that the invention is not eireumscribed by these details. lt is also to be understood that the wing 32 is not of necessity an integral formation with the horn body; indeed, the guide eye 35, if used at all, might be otherwise formed and related vto the horn body 34 without departing from the generic Character ci' the present invention, which, in its true scope, is definitely setforth in the claims.

In the present invention it will be noted of the shuttle and exterior portion of the thread leading therefrom, such as. takes place in filling replenishing looms by relative movement of the replenished shuttle and roplenishing means before the shuttle is aicked. lt will also be clear to those sliiiled in the art that such deliverable control oi' the thread having been assumed in the manner stated, the horn serves to coinplete the threading operation, and, by its retainer 31, maintains the thread depressed for proper guidance to the delivery eye 5. The wing 32 and eye 35, if used, will, in con junction with the coacting parts, insure proper direction to the thread and its maintenance in the thread passage during the weavingT operation. l'

It will be noted that the overhang 26, in

the present form of thc invention, is disposed above the tension pad 21 of felt or derstoodvthat suchidetaiis; except as detinitely pointed'oiitby the claims, are-not essential, and thatthe shuttle is primarily in tended lfor use in connection' with automatic filling replenishinglooms.
